Politologue is on course to make his return in the Shloer Chase at Cheltenham on Sunday.
The popular grey, trained by Paul Nicholls, chased home Altior in the Champion Chase at Cheltenham in March, running as well as he has ever done.
Harry Derham, assistant trainer to Nicholls, said at Kempton on Monday: "He has been a great horse for the yard and Mr (John) Hales.
"He had a breathing operation during the summer, which is something we were thinking of doing the season before last. Then he won the Melling Chase and we decided not to.

"This season, he seems a really happy horse and Paul is delighted with how he is looking. Sunday is starting point towards the Tingle Creek, but we are very much looking forward to him run.
He is one of six entries in the Grade Two along with Defi Du Seuil, Politologue, Saint Calvados and race regular Simply Ned.
French trainer Emmanuel Clayeux has also entered Nuits Premier Cru.
King said: “He will run as long as it is not heavy, but if it is heavy ground, he won’t run and the forecast is not encouraging.
“I want to run him and he is ready, but we know he doesn’t go on heavy. If it was soft I think we would let him take his chance, but any worse than that we wouldn’t.
“He is in at Ascot in a handicap, but let’s not worry about that unless we have to miss Cheltenham.
“We have had a lovely run with him and Daryl (Jacob) came in and schooled him last week and he is ready to go.”
